Could be - but why ? fuses don't normally blow for no reason.

Has the boiler been noisy lately ? more noticeable outside - maybe the fan. Inside ? maybe the pump.

There'll probably be a quick blow fuse (2amp) at the electrical connection to the boiler or on the PCB.

What's the pressure like ?? should be between 1.0 and 1.5 bar. If it#'s lower this could be why it's not working. Read instructions to see if there's any manual resets on the boiler.

Unsure - get an engineer. If you mess on you could make the problem worse and alot more expensive. Especially if you cause damage to the PCB.
